To a/ZZ whom, t may con/cern.-

Be it known that I, WILLIAM S. JACKSON,

a-citizen of the United States of America,

residing at Detroit, in the county of `ayne and State of Michigan, have invented certain new and useful Improvements in Stoves, of which the following is a specication, reference being had therein to the accompanying drawings.

The invention relates to stoves, more particularly designed for the use of bituminous fuels, and the invention consists in the novel construction as hereinafter set forth.

In the drawings, Figure l is a vertical central section through the fire-pot of the stove Fig. 2 is a horizontal section Fig. 1; Fig. 3 is a horizontal section on line @/-a Fia l- A is the base, or ash-pit section of any suitable construction, and B is the fire-pot mounted thereon. This fire-pot is formed of a series of vertically extending hollow ribs or beads O spaced about its periphery, with intermediate solid wall sections D, The spaces E, within the beads, Vform vertically extending llues which at their upper ends connect with lateral inwardly opening discharge apertures F, which are just beneath an annular flange G at the top of the fire-pot. Near the lower ends of the flues E are outwardly opening air apertures H, and these are preferably formed in a damper-ring H surrounding the lire-pot. This damper-ring is seated upon a bearing I on the fire-pot beneath the beads O, and below the ring is a shoulder bearing J seated upon the top plate or ring K of the ash-pit section.

L are apertures in the ring K, forming downward extensions of the iiues E opening into the ash-pit section.

With the construction as described, when the ring II is adjusted with its apertures I-I in registration with the flues E air will be admitted into said iiues, and discharged in a heated condition through the apertures F at the top of the fire-pot. This will cause the comparatively smokeless combustion of the distilled gases at the top of the bed of fuel, without increasing the combustion of the solid fuel in said bed. It is to be observed that the air thus admitted does not enter the ash-pit or modify in any way the regulation of drafts for admitting air through the body of fuel. It merely consumes the distilled gases and by adjusting the ring I'Il, So as to vary the extent of the openings IvI,

the proper proportion of air to the gas may be obtained. Thus, when fresh fuel is introduced into the iire-pot the damper ring H is preferably adjusted to admit a large quantity of air through the flues, and as the fuel becomes packed, and the distilled gaseslessen, the ring II may be adjusted to diminish the quantity of air. y

The openings L, through the top K of the ash-pit section, are for the purpose of permitting the ilues O to automatically clear themselves. These do not, however, affect the draft regulation, as the air entering the apertures II will be drawn upward through the flues O, and not downward. The inwardly extending iianges G at the top of the fire-pot serves to direct the hot air over the fuel, instead of permitting it to immediately rise.

My improved construction has a decided advantage over constructions in which the air is admitted through vertical slots in the inner wall of the iire-pot, for the reason that in such constructions a portion of the air will pass through the body of fuel. With my construction, on the contrary, no portion of air entering the flues can iind its way into the body of fuel. At the same time, the walls of the flues being formed integral with the firepot, the air passing therethrough is heated, and without danger of burning out the flues.

What I claim as my invention is:

1. In a stove, a fire-pot having' a series of vertically-extending 'liues communicating with the interior of the pot at their upper ends and provided at their lower ends with externally-opening air inlet apertures, an ashpit section beneath said fire-pot and downward-extensions of said flues below the externally-opening air inlet apertures forming ash discharge passages into said ash pit.

2. In-a stove, a fire-pot having a series of vertically-extending liues formed integral therewith, said iiues communicating with the interior of the pot at their upper ends and at their lower ends being provided with externally-opening air inlet apertures, an ash pit section beneath said lire-pot, downward extensions of said liues below said externallyopening air inlet apertures communicating with said ash pit, and means for variably restricting said air inlet apertures.

3. In a stove, a fire-pot having a series of vertically extending flues formed integral therewith, said liues communicating with the interior of the pot at their upper ends, and

In testimony whereof I aiiix rny signature in presence of two witnesses.
